 eral obliqual : racemes short 5-9flowered, bracts 

 ovate acute striate, calix hairy In Alabama

 only said of his Gl. comosa, leaves hirsute, ra- 

 cemes small lateral, flowers blue, seeds with 

 purple spots : it is impossible to identify it. 

 Torrey, Beck and Elliot omit it ; while Nuttal 

 deems it the real type of Gl. monoica. My des- 

 criptions and specimens will fix my sp. to which 

 1 give new names to avoid ambiguity.
